<para>The script should use <command>tar <option>cf</option></command> for the creation of the backup and <command>gzip</command> or <command>bzip2</command> for compressing the <filename>.tar</filename> file. Put all filenames in variables. Put the name of the remote server and the remote directory in a variable. This will make it easier to re-use the script or to make changes to it in the future.</para>
<para>The script should check for the existence of a compressed archive. If this exists, remove it first in order to prevent output generation.</para>
<para>The script should also check for available diskspace. Keep in mind that at any given moment you could have the data in your home directory, the data in the <filename>.tar</filename> file and the data in the compressed archive all together on your disk. If there is not enough diskspace, exit with an error message in the log file.</para>
